As promised, here's one from back in my college days. I've told it before and as in all my ghost stories is true.
I had a poltergiest in my dorm room. In the beginning of my college years, I was assigned the oddest assortment of roommates until I learned I could pay an extra $7 (!) and get a room by myself. But with or without roomies, strange things occurred. Actually, the roommates were weirder than the subject of this story - one would coo like a dove 24/7, another was into drugs and porn so I kicked her out in a matter of days, one on full valdictorian scholarship dropped out after 2 weeks of crying for her highschool boyfriend, and the final was a boyfriend stealer. The only roomie that stayed was the poltergiest.
Anyway, things you'd just sat down would be missing and later turn up right back where you'd first put it and all sorts of little funny tricks. The one I liked the best was he'd (I always thought of "it" as a "he") leave me money! About twice a week I'd find two $1 bills folded in forths in my pants or jacket pocket. I swear, I never caught anyone doing it. My friends were broke and couldn't keep a secret if they'd done it and besides none were there every year. Then there was the door that would open on it's own. We had those door knobs that required a key to open the bolt so it couldn't have just blown open. At first, I run to see who was playing tricks but no one was ever in the long dorm hallway, there were no close outside doors, and long tile floor echoed so you'd know if anyone had run down the hallway or into another room. After a while, we'd just smile and say hello to him.
The only time I wasn't bothered with him was when I got fed up with the boyfriend stealer roomie and moved to another floor. The next semester, I moved back to my original room and he was still there, but was ticked because I'd left. One day, I was standing in the room and heard a bang. The top closet storage door was on the floor right where I'd been standing. But here's the zinger, I felt the door *go through me*. Even rationalizing, there's no way that door could have fallen out of it's track and landed on the floor that far from the closet. Everyone knows how small dorm rooms are so I know exactly where I was standing and I jumped before the bang when it hit the floor. I first felt something go through me, jumped, and then heard the bang. In that order. It's the weirdest thing but I was more angry than scared. I think he got the message how angry I was with him and he never did anything mean again.
My dormitory was newer, but was an annex of older dorms so it could be our building was built on the site of another dorm. In the turn of the century era dorms, there was the usual story of the girl who committed suicide (ha, I played her in our haunted house), but there wasn't a story about my room. I've wondered if anyone else had experiences but never went back to ask.
I went to a fairly old college [1839] and lived in dorms from that time period/ Always odd sounds and sensations - and not just from roomates suffering from late-night burritos. The music hall had an especially "electric" feel about it, particularly at night and perople would swear to see shadows and things. Most music students would practice after hours but rarely too late - they just couldn't stand it. There was a story, of course, that a balcony had collapsed in 18-whenever, so who knows?
Happy Halloween!
